SPECIFICATION forming part of Letters Patent No. 770,224, dated September 13, 1904. Application filed November Z1, 1903. Serial No. 182,159. (No model.)

To L7/Z whom t may concern:

Beit known that we, DE INITT C. OHIPMAN and FRANKLIN M. REED, citizens of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented new and useful Improvements in Railway- T ics, of which the following is a specification.

Our invention has relation to improvements in railway-ties; and the object is to provide an improved compositerailway-tie which will resist all the damaging effects of time and use to which such members of a railroad-track are subjected and which will more than fulfil all the advantages of the ties now in use.

The invention embodies a metal exterior and a plastic interior body.

The invention further consists in a metal exterior, a molded composition interior body, seats for the rails, and means to hold the rails in position, all as will be hereinafter fully specified, and the asserted novelty particularly pointed out and distinctly claimed.

/Ve have fully and clearly illustrated our invention in the accompanying drawings to be taken as a part of this specification.

Reference beinghad to the drawings, Figure 1 is a perspective view of our improved tie with the rails held by thev chairs. Fig. 2 is a top plan View of the tie as applied to the rails.

Fig. 3 is a transverse section through the tie, showing one of the chairs as in engagement with the rail. Fig. 4 is a top plan View of the invention with one of the metal plates removed and showing the composition interior. Fig. 5 is a top plan view of one of the metal plates. Eig. 6 is a side View in elevation, the side plate being removed and showing the ribbed face of the filling'. Fig. 7 is a side View of one of the side plates, showing the interior face with the ribs for engaging in the composition. F ig. 8 is an enlarged transverse section through the middle portion of the tie. Fig. 9 is a detail perspective'view of the wooden cushion-block.

In the drawings the same parts appearing in the several illustrations are designated by similar reference-notations.

The metal plates which hold and clamp the composition between them are duplicates in construction and conformation, except that the fianges upon which the rails are seated are extended in opposite directions. The plates, however, are reversible, and therefore may be made from a single pattern and be applied to either side in reverse. A description of one of the side plates applies with equal pertinency to the other, and because of this the parts are designated by the same references, and referring thereto, l designates the body of the plates, made of such length and width as will conformto the length and width of the tie required. The ends of the plates are formed with turned-in flanges 2 3, and along the upper edge is an inwardly-directed flange 4. On the inner face of the plates are formed suitable ribs 5, which engage in the molded filling, the spaces between the ribs being filled by the mold, so that the side plates and the filling are held firmly united in operative relation and make a strong, useful, and durable tie. At the properl point in each plate the top flange and plate are cut away, as at 6, to form a dovetail recess, in which the end of the rail -supporting flange of the opposite plate is seated and held. At the other end portion of the plates is formed a horizontally-arranged strong rail-supporting flange 7, the side end portions of which are rabbeted, as at 8, and at the middle is a dovetail flange 9, which engages under the flange and engages in the dovetail recess 6 of the opposite plate.

10 designates the composition filling con-y tained and held clamped between the side plates. This plastic and molded composition may consist of any proper combination of materials which possesses strength and durability. The filling may consist of asphalt, concrete, slag, cement, or rock asphalt, or any other combination of artificial stone ingredients which are suitable to produce the required body for the purpose. Preferably the composition which is held between the side plates is made up of the following-named ingredients, mixed and compounded in the proportions named, to wit: Portland cement, one pound; screened gravel or sand, five pounds, which are thoroughly mixed dry.

Then these ingredients are mixed with water mortar.

until they reach the consistency of cement- Then this mixed material is placed in a mold and tamped until a moisture rises to the top. Then while in this plastic condition the compound is placed in the space between the side plates and pressed into position to take in the ribs of the side plates and completely fill the spaces between them. Then the screws are clamped up to further compress the filling, and then when the filling is solidified the tie is complete, which process takes from ten to twelve hours, and the tie is ready for use. A better compound filling may consist of creosote, cement, slag, and rock asphalt, mixed in proper proportions with gravel, and applied between the side plates in the manner above applied.

To clamp and hold the plates and the filling in position, cross-bolts 11 are projected through the parts and provided with clamping-nuts 12 on their screw-threaded ends. In the dovetail passages or seats in the railsupporting flanges are placed wooden blocks .13, filling the passages, and on which the base-flanges of the rails rest. These wooden blocks serve in the nature of cushions to relieve concussion resulting from the pressure of the wheels and protect the compound filling from the effects of the great weight imposed on it passing trains.

To hold and secure the rails in position, chairs 14 are provided, which consist of suitable metal plates arranged to lap over and bear upon the base-fianges of the rails and secured to the rail-supporting flanges of the side plates by means of screws 15 let through their outer ends and the rail-supporting fianges and secured in any preferred manner. This method of fastening the rails is convenient both for securing them or for'releasing them, as will be readily perceived by any one familiar with such devices.

Having thus fully described the invention, what is claimed as new is- 1. A composite railway-tie comprising opposite metal side plates formed with rail-supporting fianges, a filling of hardening compoysupporting fianges formed with dovetail seats therein, cushion-blocks in the dovetail seats, a filling of hardening composition between the plates, and clamping-bolts projected through the plates and filling.

11. A composite railway-tie comprising opposite metal side plates formed with ribs on their inner faces, each plate formed with dovetail recesses and a rail-supporting flange having a dovetail seat therein and the end of the fiange adapted to engage in the dovetail recess of the opposite plate, wooden cushionblocks fitted in dovetail seats of the rail-supporting flanges, a composition filling packed between the plates, and bolts to hold the parts together.

5. The combination of a railway-tie, having opposite metal side plates formed with ribs on their inner faces, each plate formed with dovetail recesses and a rail-supporting flange having a dovetail seat therein and the end of the fiange adapted to engage in the dovetail recess of the opposite plate, wooden cushionblocks fitted in dovetail seats of the rail-supporting flanges, a composition filling packed between the plates, and chairs secured to the rail-supporting flanges to hold the rails in position.

In testimony whereof we affix our signatures in presence of two witnesses.
